Actions using hpilo quite slow

[dagwieers]

I don't know if there's anything that I can debug or change to improve this, but any action using python-hpilo is quite slow. It might be due to HTTPS (and the self-signed certificate) or maybe the iLO interface is in itself slow to respond, I don't know.

Is there something I can do or test to see if we can speed up python-hpilo ? What we typically do is get facts from iLO (like interfaces, mac-addresses, hardware) and order a reboot with a specific virtual media over HTTP.

The modules that implement this are available from:

• https://github.com/ansible-provisioning/ansible-provisioning/blob/master/library/hpilo_boot
• https://github.com/ansible-provisioning/ansible-provisioning/blob/master/library/hpilo_facts

Unfortunately there's not much you can do. The XML interface for the iLO simply is slow. There's only one optimization: store the ilo type or protocol in your asset database. That way you avoid the one request overhead for each new Ilo object to find out which protocol to use (raw for ilo/ilo2, http for ilo3/ilo4)

Actually, there is a way to speed it up: iLO interfaces accept multiple commands in one XML document. In the soon to be released python-hpilo 2.0 you can use this as follows:

>>> ilo = Ilo(..., delayed=True)
>>> ilo.ilo.set_vm_status('cdrom', state, True)
>>> ilo.warm_boot_server()
>>> ilo.call_delayed()

With a bit of reordering to minimize the amount of calls to the iLO, you should be able to speed up hpilo_boot. hpilo_facts can't be sped up as it only does one call anyway.

Great to hear !

Now released, enjoy!
